چکیده
Energy harvesting system is using ambient energy conversion in the environment. The environmental will be converted into usable electrical that can used controlling wireless electronic devices. available mechanical vibration from sound then to by a piezoelectric transducer. size of represents surface area electrode on model. A smaller transducer unable produce good due area. bigger dimension model would able harvest more output because which wave energy. material Lead Zirconate Titanate (PZT-5H) focused resonance frequency at below 1 kHz with level decibel between range 35-100 dB. This research concentrate rectangular and trapezium-shaped cantilever. trapezium shaped cantilever produces higher its shape has better terms stress strain distribution. In addition, researchers have modelled validated harvesters different proof masses shapes. improved vibrational harvester trapezoidal beam an added triangular mass. arrangement tested parallel, series, combination series parallel configuration investigate performance power generated wave. are resulted resonant 269.4 Hz 269.88 Hz, respectively. produced maximum voltage 3.105 V 3.635 during array configuration, 5.636 V, 0.497 mA 2.803 mW. 81 % than compare 35.8 parallel. Thus, 5 apply several low supply applications such as mobile phones, bank or sensor networks (WSN).
